Abstract: A method and apparatus for transmitting a broadcast signal are provided. Data of data packets is encoded to add first parity data to the data packets. The data packets include broadcast data and signaling data for a service. The signaling data includes type information indicating a type of the service and channel information of the service. Information for acquisition of the signaling data is predefined. The encoded data is block interleaved. The block-interleaved data is convolutional interleaved. Transmission parameters are first encoded for signaling the broadcast data to add second parity data to the transmission parameters, and the first-encoded transmission parameters are second encoded at a code rate. A frame including the convolutional interleaved data and the second-encoded transmission parameters is built. The broadcast signal including the frame is transmitted. The transmission parameters include information for identifying a number of the first parity data.

Abstract: A method of channel assessment and channel searching in a wireless network is disclosed. The wireless network separately performs a channel assessment procedure and a channel searching procedure for channel change or another object. The channel assessment procedure is to measure a status or quality of a channel which is currently used in the wireless network. A coordinator of the wireless network designates a time interval for the channel assessment to notify other device of it. The channel assessment procedure may be performed periodically, and is preferably scheduled to allow other devices not to use the channel for the time interval which at least one device performs channel assessment.

Abstract: A method of allocating channel resources in a wireless network is disclosed. The method of allocating instant channel resources in a wireless network includes receiving channel resource scheduling information of a specific superframe from a coordinator of the wireless network, requesting the coordinator to allocate instant channel resources for an unreserved duration of the specific superframe, and receiving an announcement message from the coordinator, the announcement message announcing allocation of the instant channel resources within the unreserved duration of the specific superframe.
